Abstract :
MPEG-1 is a successful international standard for video and audio coding, and has been widely used in many fields, such as entertainment, education, digital library, video on demand etc. As the MPEG-1 stream has its own semantic structure, the multicast application may destroy its syntax which results in decoding failure. To deal with this problem, a novel random access method is proposed in this paper to repair the corrupted stream structure. This solution consists of two main steps: first, it should extract necessary information from the multicast stream, and then a system header would be constructed using the information, whereafter this header would be inserted to the beginning of the decoder buffer. By this way, the decoder can play the received multicast stream without any problem
